Is the #808 a better/gentler fit staying with a stock motor... figuring upping to 48v, 2guage wires and the 808 controller?.. and to add another thought that has come up.. I've noticed that with less pressure in the tires, 7lbs, the cart seems to be a bit more stable than with 15... at 15 lbs, the cart has a mind of it's own, it swerves at top speed.. I'm guessing that's the compromise, pressure up to what I want and need.....
